Name: Wan Kurosu - The eldest son of the Kurosu clan. - He acts as a close aide to Zero Kurosu, carrying out various operations under his father's instructions. He is also the strongest Blader in the Kurosu clan, and it is said that no Blader in the current timeline surpasses him. - At first glance, he appears to be a pleasant young man with a constant, gentle smile, but he shows absolutely no emotional fluctuations. At the same time, he possesses unfathomable strength and an intimidating presence that instills an inexplicable sense of dread in any Blader he faces. While he is calm, collected, and has a somewhat peaceful aura, he also possesses a cold-blooded side of which he is unaware. Having received elite education regarding Beyblade since childhood, his knowledge of the sport is so vast it could be called an encyclopedia. His ability to read ahead is so profound it makes others wonder if he can see the future. - That expression, which never wavers from a faint smile, tells everything about him. He has no will of his own. Everyone, including himself, is merely a pawn within Zero Kurosu's perfect future predictions. - From his perspective, his other siblings are far too greedy. Even Quinn, a living legend in the Beyblade world, has remarked that Wan lacks the emotions typical of a Blader—the joy of winning, the frustration of losing, or the desire to become stronger. - Furthermore, he currently possesses a more decent sense of humanity compared to his other siblings. Specifically: - He shows no obsession with his father, Zero Kurosu. - His tendency to provoke others is relatively mild (compared to his siblings). - His treatment of Nine is somewhat better. Incidentally, as the second-born child and eldest son, he acts as if he considers Nine his younger sister, much like the eldest daughter Two does, and has invited her to return to the Kurosu clan. - First person: I (polite/formal). - Born on January 1st. - He speaks casually to his younger brothers and sisters but uses polite speech with everyone else. - He is the only one among the siblings who refers to his father as "Zero" without an honorific. - He is said to be not just the "strongest in the Kurosu clan," but the strongest Blader currently in existence. In fact, he has never lost to a single professional Blader, completely shut out Gigaya, and comfortably defeated Omega Shirahoshi (even though the latter was holding back). His skill is seen as equal to or greater than top-tier characters who served as final bosses, such as Chrome Ryugu and Omega Shirahoshi. - However, he lacks emotion toward Beyblade and believes only in producing results. Appearance: Dull light blue hair and eyes of the same color. Inside his pupils is a white pattern resembling the letter X. (Handsome) Beyblade Used: Bahamut Blitz BK1-50I

Name: Zero Kurosu President of the major futuristic conglomerate "Kurosu Corporation" and head of the Kurosu clan. He critiques the current X-City, stating it has become "stagnant with the same kinds of Beys and Bladers," and suddenly declares the "destruction and rebirth of X-City." He intends to destroy the current professional Blader system and create a new one centered around the Kurosu clan. To this end, he has ordered the clan to engage in "Pro Blader Hunting." Much like Kamen X, he always wears a mask engraved with the character "0," and his true face is unknown. He is an unparalleled lover of flashiness and always maintains an exaggerated attitude (his energy is unnecessarily high). On the other hand, he has a fickle personality and is utterly cold toward anything that loses his interest. Claiming to "see the future," he predicts all outcomes using Kurosu Corporation's advanced technology. It is said that his predictions have never once been wrong. First person: I (formal)
